SHlNGLE-PACKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 495,403, dated April 11, 1893. 7

Application filed October 27, 1892. Serial No. 450,169. (No model.)

To all whom it may concern.-

Be it know'n that I, WILLIAM H. DUTTON, a citizen of the United States of America, residingatBeaver, in the county of Marinette and State of Wisconsin,have invented certain new and useful Improvements in Shingle-Packing Machines; andI do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in machines for packing shingles.

The object of the invention is to provide a shingle packing frame and press in which the bundle or bundles of shingles can be compressed and tied; and it consists in the construction and combination of the parts, as will be hereinafter fully set forth and particularly pointed out in the claims.

' Y In the accompanyingdrawings forming part of this specification: Figure 1 is a perspective View of a shingle packing machine constructed in accordance with my improvements. Fig. 2 is a longitudinal section, and Fig. 8 is a detail view.

A designates a suitable frame having supporting legs which may be provided at their lower ends with means for lengthening and shortening the same, so that the machine may be set at the proper height to suit the operator. The legs, a a, are braced by suitable cross pieces I) b, and are connected near their upper ends by longitudinal beams o o and transverse pieces I) b. To one of the transverse pieces I) is hinged a board or guide B, while to the other transverse piece I) is rigidly attached a similar board or guide B, which is also secured to the upper ends of the corner-posts or legs.

To about the central portion of each side beam 0 is rigidly secured a casting cl, having an aperture through which passes a presserbar. The aperture is a little larger than the resser-bar so as to permit said presser-bar to have a slight play therein. A spring (1 bears against the rear side of each presser-bar to force the same toward the shingle or shingles, the movement being sufficient to prevent the jamming of the cross-bars forming a part of the clamp which holds the shingles together.

Between the corner-posts of the machine, and below the side beams c o are rigidly secured horizontal beams D D. These beams are recessed or cut away on their inner sides, and about centrally, to receive the lower end of the presser-bar, and to the under side of each beam is attached a casting or bearing 6 provided with an aperture or slot on a line with the cut-away portion of the beam. A shaft E passes through these castings or bearings so as to intersect the slot to one side of the presser-bar, and upon this shaft, so as to be located within the slots, are keyed toothed segments G G. Each segment is provided opposite its toothed portion 9 with an offset or lug g slotted to receive the lower end of a bar H which is pivoted thereto, said bar passing up through the casting 61 into a vertical groove formed in the presser-bar, the upper end having an oifset h which projects without the groove. The teeth of the segments engage with teeth formed on the lower ends of the presser-bars I, and it will be noted that as the shaft is rocked the bar H will move in an opposite direction from the movement of the presser-bars. The shaft E is rocked by means of a foot-lever K, which is pivoted on a cross-rod k and has a downwardly extending arm is which is connected to a crank portion in the shaft E by means of a link L. It will be noted that the foot lever-extends immediately above the crank portion in the shaft, so that when it is depressed it will lie within said crank portion.

In operation the foot-lever is raised to project the presser-bars I and retract the bars H; a strip or board is then placed across the frame beneath the hooks formed in the upper end of the presser-bars and upon the castin gs d d, a bandor tie being preferably placed beneath the board so that the ends thereof will extend into the grooves formed in the presser-bars and beyond the same. The shingles are then laid within the frame in the usual manner, and another board or strip placed upon the shingles and beneath the projecting ends of the presser-bars. The lever is then depressed to clamp the shingles between the boards, when the ends of the band or tie are brought together and secured.

By simply raising the foot-lever the bunch or bundle of shingles will be released and can be readily removed from between the presserbars, as the springs d hereinbefore referred to permit said presser-bars to spread sufficiently for the purpose.

I am aware that prior to my invention it has been proposed to provide a machine for packing shingles with clamps having the up, per ends bifurcated and provided with hooks; also that it is not broadly new to provide a shingle packing frame With clamps which move to and from each other when a transverse shaft is partially turned, and I therefore do notclaim such construction; but

What I do claim as new, and desire to secure by Letters Patent, is

1. In a shingle packing machine, the combination of a pair of movable clamping bars I and H, the bars I having teeth, together with a cross-bar provided with toothed segments G and offsets to which the bars H are pivotally attached, substantially as shown, and for the purpose set forth.

2. In a shingle packing machine, the combination of the clamping bars H. and Iwhich are passed through castings, a cross-bar E having a crank portion with which a connecting link engages, said connecting link also being attached to' an operating lever, of toothed segments G G adapted to engage with the teeth on the clamping bars I, the bars II being pivoted at their lower ends to offsets formed integral with the segments, substantially as shown, and for the purpose setforth.

3. In a shingle packing machine, the combination of the castings d (1 having apertures through which pass the clamping bars, springs cl cl adapted to bear against the rear side of v the clamping bars I I, the width of said clamp-
